I don't have any experience with the SD humbuckers but I saw this and thought I'd bring it backup for you. Hopefully you will get more responses.
Dude, you have some sweet amps and cabinets! Are you a famous rocker in Norway? But, then again I've heard the standard of living there is one of the worlds highest and you are reaping the benefits.
If I were putting a HB in a strat I would choose the Custom Custom. Put a couple pedals after it and you could get as hard and heavy as you want. DuckBuckers get good reviews they would probably work out great.
A full size JB would also be great.
I think you're in a win/win situation. Whatever you choose, you can make it work. It'll rock.
Can't wait to see what others suggest and what you go with.
